Poison Dart frogs live in tropical rainforests of Central and South America. They are amongst the most poisonous species on Earth. They are small and have bright colored bodies. Their bright color indicates their toxicity to predators. Scientists think that the toxicity of these frogs comes from the insects they eat.
In future, due to very less rainfall and forest degradation tropical rain forests will convert into Shrublands with mild, wet winters and long dry summers. To adapt to long, hot summers, these frogs will have to develop thick, impermeable skin to prevent water loss. They will lose their bright colors due to changes in diet and may develop lighter skin color to camouflage. They may also develop small storage pouches under skin to store water for hot, dry summers. They may have to adapt to living in the burrows under soil to protect from extreme heat.
